Abstract
The present invention relates to specific compositions made by alkoxylation of crude guerbet alcohol mixtures that contain between 15% and 50% lower molecular weight alkoxylated alcohols. The lower molecular weight alcohols are the raw material alcohols used to make the guerbet. Compositions containing this specific bi-modal distribution have unique emulsification properties.
Claims
exact text as granted — not AI-modifiedWe claim:
1. A bi-modal emulsifier composition which comprises:
(a) between 10% and 50% by weight of an emulsifier which conforms to the following structure:
CH 3 (CH 2 ) n− O—(CH 2 CH 2 O) a (CH 2 CH(CH 3 )O) b —(CH 2 CH 2 O) c —H
wherein;
n is an integer ranging from 5 to 19;
a, b, and c are independently each integers ranging from 0 to 20, with the proviso that a+b+c be greater than 5;
and
(b) between 90% and 50% of an emulsifier which conforms to the following structure:
wherein;
y is an integer ranging from 5 to 19, and is equal to n;
x is an integer ranging from 3 to 17 with the proviso that x=y+2
a, b, and c are independently each integers ranging from 0 to 20, with the proviso that a+b+c be greater than 5.
2. A bimodal composition of claim 1 wherein n is 5, x is 3 and y is 5.
3. A bimodal composition of claim 1 wherein n is 9, x is 7 and y is 9.
4. A bimodal composition of claim 1 wherein n is 7, x is 5 and y is 7.
5. A bimodal composition of claim 1 wherein n is 11, x is 9 and y is 11.
6. A bimodal composition of claim 1 wherein n is 19, x is 17 and y is 19.
7. A bimodal composition of claim 1 wherein a+c ranges from 10-40.
8. A bimodal composition of claim 1 wherein a+c ranges from 10-40.
9. A bimodal composition of claim 1 wherein a+c ranges from 10-40 and b ranges from 1 to 20.
10. A process for making an emulsion, which comprises mixing;
(4) between 1% and 50% by weight of a water insoluble oil,
(5) between 98% and 35% water
and
(6) between 1% and 15% by weight of bi-modal emulsifier compositions, which comprises:
(a) between 10% and 50% by weight of an emulsifier which conforms to the following structure:
CH 3 (CH 2 ) n− O—(CH 2 CH 2 O) a (CH 2 CH(CH 3 )O) b —(CH 2 CH 2 O) c —H
wherein;
n is an integer ranging from 5 to 19;
a, b, and c are independently each integers ranging from 0 to 20, with the proviso that a+b+c be greater than 5;
and
(b) between 90% and 50% of an emulsifier which conforms to the following structure:
wherein;
y is an integer ranging from 5 to 19, and is equal to n;
x is an integer ranging from 3 to 17 with the proviso that x=y+2
a, b, and c are independently each integers ranging from 0 to 20, with the proviso that a+b+c be greater than 5.
11. A process of claim 10 wherein n is 5, x is 3 and y is 5.
12. A process of claim 10 wherein n is 9, x is 7 and y is 9.
13. A process of claim 10 wherein n is 7, x is 5 and y is 7.
14. A process of claim 10 wherein n is 11, x is 9 and y is 11.
15. A process of claim 10 wherein n is 19, x is 17 and y is 19.
16. A process of claim 10 wherein a+c ranges from 10-40.
17. A process of claim 10 wherein b ranges from 1 to 20.
18. A process of claim 10 wherein a+c ranges from 10-40 and b ranges from 1 to 20.Cited by (0)
